Abstract:
l'hc experiment was conducted with a view to investigate the pre-planting
hardening of seedling on the performance of inbreed and hybrid aman
rice at
Sher-e-Bangla Agricultural University. Dhaka-1207. Bangladesh during aman
season (July to December. 2013). The experiment was carried out with three
varictics i.e. BRRI dhan53. BRRI hybriddhan4, and Pajam and five seedling
hardening treatment methods viz, direct transplanting (Tt), storage in shade
condition for three days (T
2 ), storage in open field condition for three days (1)).
storage in water condition for three days (F4
) and storage in cool air condition
for 24 hours (T5
). This experiment was laid out in a randomized complete block
design (factorial) with three rcpli cations. Results revealed that in open field
condition. Pajam variety was significantly increased in plant height. number of
effective tillers, leaf area index (LAI) and total dry matter (1DM) at 30DAT
and 45DAT, respectively but later on BRRI hybriddhan4 showed the highest
result. Yield attributing parameters, such as panicle length. grain number
panicle* 1000 grain weight and yield were improved due to the treatments.
The highest grain yield (7.26 t ha") was in BRRI hyhriddhan4 under open field
storage condition. however. the lowest grain yield (2.31
1 had
) was found in
BRRI dhan53 with direct transplanting combination
